#Tetanus shots prevent dangerous infections

The purpose of a tetanus shot

Everyone should get tetanus shots as recommended. A tetanus shot is a vaccine that protects you from getting tetanus. Tetanus, also called “lockjaw,” is a serious disease caused by bacteria called Clostridium tetani. When you get tetanus vaccines as recommended, your body makes antibodies, special proteins that will help your immune system fight the toxin produced by the bacteria.

Clostridium tetani are bacteria that live in soil and manure. Tetanus infections most commonly happen when you suffer a wound that gives the bacteria a chance to enter your body. For example, stepping on a nail is a common cause of tetanus infections. Once inside your body, the bacteria release a toxin that causes your muscles to tighten. This can cause your mouth to “lock” shut and make it hard to swallow. If not treated promptly, the muscle stiffness spreads and, in some cases, can cause death.

A tetanus infection can enter the body through small cuts, scrapes, and scratches. If you’re cut by a metallic or rusty object or suffer a deep wound, immediately consult a doctor about receiving a tetanus shot. Keep in mind, tetanus infections can also occur as a result of burns, animal bites, or wounds contaminated with dirt or faeces.

Good wound care and prompt treatment reduce the risk of developing a tetanus infection, but the tetanus vaccine is the best way to protect yourself from the disease. Tetanus does not pass from person to person, so “herd immunity” cannot prevent tetanus infections. You also do not build immunity to future tetanus infections by having had a previous infection. As a result, each person needs a series of tetanus vaccines in order to avoid getting tetanus. Tetanus vaccines are often given in combination with vaccines that protect you from other diseases, such as diphtheria and pertussis.

Tetanus boosters help to make sure that you have enough antibodies to neutralize the toxin produced by Clostridium tetani should you get an infection. If you are injured and it has been more than 10 years since your last tetanus booster, your doctor may recommend getting a booster shot. If your wound is especially dirty, your doctor may recommend a booster shot even if it has been less than 10 years since your last tetanus shot.

When to seek medical advice

You should contact your GP if you're concerned about a wound, particularly if:

Ø  The wound is deep

Ø  The wound contains dirt or a foreign object

Ø  You haven't been fully vaccinated against tetanus

Ø  You're not sure whether you have been fully vaccinated against tetanus

Ø  Your GP can assess the wound and decide if you need a vaccination or any other treatment.

Ø  You may need additional treatment for a serious or dirty wound that's considered to be tetanus-prone.

Ø  You should immediately go to your nearest hospital or call an ambulance if you develop severe muscle stiffness or spasms.
